Only when a technology and application collide with a certain degree of convergence can a plate heat exchanger truly show the vitality of an industry. In 2008, China's semiconductor lighting (LED) application products exceeded 45 billion yuan plate heat exchanger unit Compared with 2007, it shows a rapid growth trend.
Functional landscape lighting, LED full color display, solar LED, consumer electronic backlight, signal, indication and other applications are still the main application areas (energy saving is above 70%) Nanjing Pilsen accounts for 60% of the application market; functional municipal Lighting applications grew faster in 2008 Alfa Laval plate heat exchangers have hundreds of thousands of LED demonstration street lights, tunnel lights have been applied (energy saving has reached 50%); LED in LCD-TV (LCD TV) backlight and car lights Some high-end applications have also made some progress.
In 2008, the distribution of LED products in various major application areas showed that the architectural landscape is the largest application area of ​​LED in China. Alfa Laval plate heat exchanger units account for 28% of the total market share; LED display and home appliances display domestic LED Plate-type heat exchangers account for 27% of the total market share in the two application fields; small and medium-sized backlights such as mobile phones and computer notebooks account for 22% of the total market share of plate heat exchangers in the third application field; traffic lights, car lights, Various types of applications such as special lighting have a certain market share.
Landscape lighting: Semiconductor lighting has significant features such as power saving, rich change, bright color and long life. Nanjing Pilsen is widely used in landscape lighting projects. In 2008, the domestic landscape and decorative lighting market scale was 13 billion yuan Alfa Laval board. The heat exchanger is only used by the Beijing Olympic Games LED landscape lighting for nearly 500 million yuan. With the construction of Shanghai World Expo 2010 and the urbanization process, the application of Alfa Laval plate heat exchanger unit LED in landscape lighting will further increase its proportion.
LED display: In 2008, the LED display market was about 10 billion yuan. With the Beijing Olympic Games, Shanghai World Expo, Guangzhou Asian Games and other major events, the plate heat exchanger stadiums, airports, stations, banks, hospitals, public The market application space of LED display screens for large-area application of plate heat exchanger units in squares, commercial places and residential communities is constantly expanding.
Digital display and indication of home appliances: In 2008, the market scale of LED home appliances digital display and instruction was 2 billion yuan. With the government's policy of “home appliances going to the countryside†and the improvement of living standards of urban residents, the purchasing power is enhanced. Nanjing Pilsen China Appliances Consumer demand for products has soared. The LED signal and indicator module has become a necessary accessory for digital home appliances. Alfa Laval plate heat exchangers have also won development opportunities.
Backlights for mobile phones, computers, etc.: In 2008, the market for LED backlights such as mobile phones, mp4s, computers, and televisions was 10 billion yuan. With the continuous development of liquid crystal display technology, the application fields of Alfa Laval plate heat exchanger units are also expanding. The backlight industry has shown a booming scene. It has gradually begun to replace CCFL (Cold Cathode Fluorescent Lamp). It has become a trend of backlight development.
Traffic signals and indicators: In 2008, all new and expanded roads used LED traffic lights. The traffic signals of most cities in China have also completed LED transformation. The market size is about 2.5 billion yuan.
Automotive lighting: At present, automotive applications are mainly based on interior lighting and signal lights. With the breakthrough of power LED technology, the future headlights will also use LED as the main light source. In 2008, the automotive lamp (except the headlights) LED market scale It is about 1 billion yuan. It is becoming an important application market for LED.
Special lighting: With the popularization of LED products in special lighting fields such as flashlights, miner's lamps, explosion-proof lamps, beacon lights, etc. LED has gradually replaced other lighting sources to become the mainstream of such products; solar lights, stage lights, ship lights, emergency lights The proportion of LED lamps used in reading table lamps has also increased rapidly; emerging application markets such as UV disinfection, medicine, and agriculture are also emerging. In 2008, the market size of LED special lighting products was about 2 billion yuan.
LED street light: In 2008, the market size of LED functional lighting products was about 1 billion yuan. The use of municipal lighting grew rapidly. Among them, LED street lights are the main ones, accounting for about half of the market. According to the statistics of the Urban Road Lighting Professional Committee of China Municipal Engineering Association. In 2008, the total number of street lamps in China was about 15 million baht. In the future, about 2 million new street lamps will be added each year. According to the current development speed and trend, the government can effectively guide and promote from the perspective of energy conservation and emission reduction. LED street lamps will become LED's largest application area and market.
LED Tunnel Light: China is the country with the most tunnels in the world. In 2007, the number of tunnels was 4,673. The length of the tunnel was 2,55,500,000 meters. According to the "Design Specification for Ventilation and Lighting of Road Tunnels (JTJ026.1-1999)". Tunnel lighting (by average) The length of 547 meters is calculated to be 1.6 million. Currently, there are more than 10 provinces and cities in Shanghai, Guizhou, Shaanxi, Jiangxi, Zhejiang, Yunnan, Chongqing, Anhui, Guangdong, Fujian, etc. There are about 12 LED tunnels with more than 30 kilometers. The pilot application of the lamp has achieved good energy-saving effects. The application of the LED tunnel light has a huge market potential.
Metro lighting: Guangzhou, Shenzhen, Hong Kong and other places have begun to use LED functional lighting products in subway pedestrian passages, platforms, cars, light boxes, etc. From the perspective of China's planned preparation and construction of rail transit cities. Future LED subway lighting It will also become a very important application market.
Gas station and underground parking lot lighting: In 2008, the number of Chinese civil cars was more than 20 million. For example, 20% of civilian cars use underground parking lot. According to the "Architectural Lighting Design Standards", the annual underground parking lot needs 36W fluorescent lamps 200. Ten thousand; each domestic gas station uses 10 ç› ceramic metal halide lamps and indicator light box lighting. There are about 94,000 gas stations in China. Although the development and application of this aspect has just started, the potential is huge.
With the further development of technology, the application market structure of LED will also undergo great changes in the future. It is expected that the overall scale of China's semiconductor lighting market will reach 100 billion yuan in 2010. The scale of LED backlight market will exceed landscape decoration lighting. The largest application area. The market size of functional and general lighting will also grow rapidly. It is estimated that the compound annual growth rate from 2010 to 2015 is expected to reach 40%. In 2015, the industry scale will reach more than 500 billion yuan.
